This thesis discloses my exploration of non-isochronous meters through composition and practice. During my two-year studies at the Royal College of Music in Stockholm, I explored different unevenly divided time signatures by practicing them in various ways, producing transcriptions, compositions and arrangements.The main purpose of this project was to further my knowledge and skills within these time signatures and thereby expand my horizon on perceiving, conceptualizing, composing and playing them. My endeavors culminated in seven original compositions, arranged for a jazz sextet, which I rehearsed and performed with an ensemble. During the process of composing, arranging, practicing and rehearsing, I gained a lot of articulated knowledge as well as embodied knowledge of the idiosyncrasies of various non-isochronous meters and different ways to perceive and play them.

Homes with integrated state of the art technology are considered Smart Homes. A smart home has special systems which enable remote control via remote computer or smart phones. These modern integrated services are supported by electrical power infrastructures called Smart Grids, which provides a stable electrical power environment to support all functionalities, with intelligent power systems that provide increased power quality. Inside a Smart home, a legacy metering system called Smart Meters are installed offering new functionalities such as remote readings of power consumption, and different time usage of tariffs.Preliminary research has already indicated vulnerability attacks on smart meters which affect the security and privacy in smart meters. Security issues in this system include vulnerabilities and privacy issues includes information leakage in real-time consumption data that is recorded by the smart meters.Enhancing both security and privacy in the smart meters are the main purpose of this thesis. The principle goal of this research is to provide more understanding about the smart meters from a security and privacy perspective. This thesis investigates issues and problems in smart meters and proposes a secure communication protocol in the application layer, in addition to a proof-of-concept of the final solution. In this research we introduce the solution by means of two scenarios, we highlight the effects of an attack on the smart meters on levels of simulation and theory. The first scenario is to "take control over the smart meter to access the data consumptions in the smart meters". The proposed solution of using the Smart Phone as a third part to protect the smart meters has been evaluated using a network simulation tool. The result shows that the data captured by attacking node is encrypted and can't be used for any useful operation. In the second scenario, "monitoring the data consumptions to harm the user's privacy", in other words, stealing the user's devices. The proposed solution is using the home electrical power routing to moderate the home's load signature in order to hide appliance usage information. Data clusters are implemented as a proof of concept to evaluate the data. The results show that there is only 99.5 % correct clustered data with good quality.

ABSTRACT South Africa, like numerous other developing countries throughout the world, faces increasing demands for public services in urban areas (Rondinelli and Kasarda, 1993). South Africa’s access to basic services such as water has clearly become part of social security/ citizenship. The research report investigates and elucidates the role of privatisation in the basic service delivery context. It argues that the GEAR policy framework blocks the resources required to achieve social citizenship (Cock 2000). This gave rise to community struggles concerning prepaid water meters in Phiri, Soweto. These struggles are examined and competing discourses surrounding public versus private sector participation in basic service (water) provision are also explored. The argument in this research report is two-fold. First, it establishes a view of water as an economic good, with the democratic government reducing the municipal problems of delivery to economic markets or private corporations. Second, it examines the perspective that water is a human right issue contained in the Bill of Rights. These two counter-arguments perpetuate struggles in relation to access, affordability and supply of water. The research seeks to examine these opposing arguments and further explores the impacts these struggles have on future delivery and access of such ‘life need’ as water. This exposure is done through the collection of Secondary data and empirical evidence obtained using various qualitative data gathering techniques. Although the advantages of prepaid water meters are recognised, the dominant argument in this report is in line with Dependency Theory. This maintains that the socio-economic inequalities as well as the socio-environmental injustices widespread in the policies of privatisation exclude various sectors of the population from full access to essential necessities such as water. These injustices are rooted in the fact that water is treated as a commodity to be sold and not as a basic human right (Maema 2003). To deny water to people reduces their citizenship and therefore the achievement of full citizens’ rights for the community of Phiri has become one of the crucial barometers for the realisation of the depth and sustainability of South Africa’s democracy (Khunou 2000). The research findings obtained suggest that the government does realise its responsibility to provide basic water services. Nevertheless, it delegates this responsibility to private institutions; hence making it an individual responsibility to gain access to water at a cost. This form of attempt in South Africa gives a clear reflection of Adam Smith’s “commercial society” which is viii encompassed and endorsed by privatisation and the capitalist endeavours. However, this is in contrast with the principles enshrined in the constitution of the Republic of South Africa, which mandate the government to ensure the progressive realisation and maintenance of access to available basic services. The research report, however, suggests that some educational programmes need to be developed and promoted to inform and equip the public on how best to preserve water. This endeavour is gradually envisaged under the auspices of emerging corporatised utilities.
